We test whether Hofstede (1980) cultural dimensions affect accounting conservatism in the banking sector. Our sample is 3593 banks-year observations from four countries. We find significant positive effect of uncertainty avoidance and power distance on accounting conservatism and a significant negative effect of individualism and masculinity on accounting conservatism. We robust our findings using cultural dimensions of House et al. (2004). We contribute to the literature as follows. First; we focus on the banking sector that has been marginalized by many researchers. Second; we cover the most recent period from 2013 to 2020. Third; we found new evidences of the significant relationships between the four dimensions of Hofstede (1980) and accounting conservatism in the banking sector. Fourth; the random effect method for panel data for regression is used in this study to control fixed years effect which enabled us to explain the role of culture in accounting conservatism.

El-Deeb, M. S., Y. T. Halim, and A. F. Elbayoumi, "Disclosure tone, corporate governance and firm value: evidence from Egypt", Asia-Pacific Journal of Accounting and Economics, vol. 29, 2022. Abstract

This study examines the extent to which corporate governance (CG) affects disclosure tone (DT) and assesses the impact of DT on firm value (FV). It also tests the effect of CG on FV using DT as an intermediary variable. Content analysis is used to measure DT level. CEO duality, board size, gender diversity, and board independence are used as proxies for CG. Tobin’s Q is used to measure FV. The empirical analysis shows significant positive impact of CG on DT and FV. We also find a highly significant association between disclosure of good/bad news with leverage, audit quality, firm growth, and abnormal accruals. The results also indicate that DT along with the profitability of the firm (ROA) and Abnormal Accruals are significantly associated with FV. Finally, the results of the structure equation modeling show that gender diversity, ROA, leverage, revenue growth, and abnormal accruals are the most influential variables that run from CG and DT into FV. The novelty of this study stems from its empirical analysis that tests the association between CG, DT from one side and DT and FV from the other side, and then measures the impact of CG on FV using DT as an intermediary variable.

Research Questions: In what ways does the corporate governance scorecard (CGSC) and internet reporting intersect with audit quality? To what extent do technological advancement and auditor qualifications moderate the association between internet reporting, corporate governance (CGSC), and audit quality? In what capacity does audit quality mediate the association between internet reporting and the corporate governance scorecard (CGSC)? Motivation: The rationale for conducting this study is to fill a known void in the academic literature concerning corporate governance in developing nations, with Egypt serving as an example. Idea: The main idea of our study is to understand the impact of CGSC-measured corporate governance on internet reporting of financial and non-financial information. Our study also seeks to determine whether audit quality acts as a mediator and whether auditor qualifications and technological advancement moderate this relationship. Data: Using a questionnaire, 258 auditors from various auditing firms, including the Big4 and national audit firms with international affiliation, data were collected. Tools: Factor analysis, Pearson correlation, and Structure Equation Modelling. Findings: Corporate governance assessed by CGSC improves the Internet reporting through the mediation of audit quality, with auditor qualifications and technological advancement serving as moderators. Contribution: This study contributes to the scholarly comprehension of the association that exist among CGSC, audit quality, and internet reporting. Implications for utilizing CGSC as a metric for evaluating corporate governance practices and its influence on online reporting are both theoretical and practical in nature. The investigation contributes valuable perspectives that can guide decision-making in practical and theoretical settings, thereby enhancing the academic discourse.

The board diversity is a vital factor influencing corporate sustainability by incorporating varied perspectives and expertise into environmental, social, and governance (ESG) practices. This study examines the impact of board diversity—gender, age, educational background, and nationality—on sustainability performance in UK-listed companies. Grounded in Stakeholder Theory, Resource Dependence Theory, Critical Mass Theory, and Institutional Theory, and using quantile regression, this research explores these relationships across sensitive and non-sensitive industries over a 20-year period (2002–2021) using data from 1814 companies. The sample is segmented into high-, medium-, and low-sustainability companies to assess the heterogeneous effects of diversity. Findings reveal industry-specific patterns: In sensitive industries, gender diversity negatively affects ESG scores in low- and medium-sustainability companies, while nationality diversity consistently improves ESG outcomes across all levels. In non-sensitive industries, age diversity enhances ESG scores in medium- and high-sustainability companies, whereas educational diversity shows mixed effects—negative in medium and positive in high-sustainability companies. Nationality diversity also positively impacts ESG outcomes in medium-sustainability companies. This research adds to the literature by looking at how board diversity impacts sustainability performance across industries and sustainability levels by combining a multi-theoretical approach and applying quantile regression, as well as practical guidance for companies looking to improve board diversity for better sustainability performance.

Kandil, N., M. A. K. Basuony, M. Bouaddi, H. Elmoursy, and A. F. Elbayuomi, "Examining CEO Characteristics and Carbon Emissions: A Quantile Approach to UK-Listed Firms", Sustainability, vol. 17, no. 13, 2025. AbstractWebsite

This study aims to empirically examine the effects of CEO characteristics (gender, nationality, multiple directorships) on the carbon emissions of UK-listed firms. We focus on understanding how these factors influence carbon emissions across the overall sample and within specific industry sectors grounded on the upper echelons and stakeholder theories. We employed a quantitative research design using quantile regression analysis. Our dataset comprises 295 UK-listed firms from the STOXX 600 Index of European-listed companies, covering the period from 1999 to 2023. Data were sourced from BoardEx, Refinitiv DataStream, annual reports, and sustainability reports. Our results indicate that foreign CEOs are associated with higher carbon emissions across the overall sample of UK-listed firms, across the three levels of carbon emitters within the sensitive industries, and within low- and high-level emitters within the non-sensitive industries. CEOs with multiple directorships were found to have a significant association with higher carbon emissions, likely due to divided attention and obligations. As for the CEO gender, it is noteworthy that it has an insignificant effect on reducing carbon emissions in low emission companies within sensitive industries. In contrast, female CEOs were associated with lower carbon emissions in medium-emitting firms within non-sensitive industries. This study contributes to existing literature by employing sensitivity analysis (sensitive sectors and non-sensitive). The study also employs a novel econometric technique, quantile regression, which provides a comprehensive understanding of the relationship between independent and dependent variables across different points of the distribution.
